JSON Serializer & Deserializer

Saya ingin berbagi sedikit tips mengenai JSON serializer dan deserializer yang ada di ASP.NET AJAX. Dengan menggunakan ASP.NET Ajax pertukaran data antara client (JavaScript) dengan server menjadi gampang banget. Kita tidak perlu lagi pake XMLyang rumit. Dengan JSON data mudah banget di-parse.

Contoh code di client (JS):

function getFilterData() { var dateFormat = '<%= HelpdeskSystem.DateFormat %>'; var filter = { instance: $get('<%= instanceList.ClientID %>').value, requestNo: $get('<%= requestNoTextBox.ClientID %>').value, category: $get('<%= categoryList.ClientID %>').value, itemCategory: $get('<%= itemAffectedList.ClientID %>').value, ticketGroup: $get('<%= ticketGroupList.ClientID %>').value, status: $get('<%= statusList.ClientID %>').value, requestType: $get('<%= typeList.ClientID %>').value, startDate: Date.parseLocale($get('<%= dateFromTextBox.ClientID %>').value, dateFormat), finishDate: Date.parseLocale($get('<%= dateToTextBox.ClientID %>').value, dateFormat), requestedFor: $get('requestedForEmployeeId').value, assigneeId: ($get('<%= assigneeForEmployeeId.ClientID %>') != null) ? $get('<%= assigneeForEmployeeId.ClientID %>').value : $get('<%= assigneeForEmployeeIdLabel.ClientID %>').innerHTML }; return Sys.Serialization.JavaScriptSerializer.serialize(filter); // Serialize object to JSON string }

Di server side (C#), tinggal di-deserialize. Dalam hal ini saya pake data JSON tersebut pada event CallBack Janus Grid:

protected void GridEX1_CustomCallBack(object sender, Janus.Web.Common.CustomCallBackEventArgs e) { System.Web.Script.Serialization.JavaScriptSerializer jsSerializer = new System.Web.Script.Serialization.JavaScriptSerializer(); var edata = System.Web.HttpUtility.UrlDecode(e.EventData.ToString()); var data = jsSerializer.DeserializeObject(edata); // data selanjutnya di prosess di sini }

Simple banget.

Hasil deserialize object ketika debugging tersebut dapat dilihat seperti gambar di bawah.


Dari gambar tersebut, string JSON telah di-deserialize menjadi object (string, Date, dll). Mudah bukan?

Semoga bermanfaat.

In ASP.NET AJAX Extensions v1.0 for ASP.NET 2.0 there is the JavaScriptSerializer class that provides JSON serialization and deserialization functionality. However, in .NET 3.5 the JavaScriptSerializer has been marked obsolete. The new object to use for JSON serialization in .NET 3.5 is the DataContractJsonSerliaizer object. I'm still new to the DataContractJsonSerializer, but here's a summary of what I've learned so far...

Can anyone point me to some JSON serialize / deserialize how to's? I know I ran across some examples earlier last week but I can't remember where I found it.

JSON (JavaScript Object Notation) is an efficient data encoding format that enables fast exchanges of small amounts of data between client browsers.
